The Enterprise returned one day later, but the Pegasus was too deep within the asteroid to be accessed by transporter or shuttlecraft. Against CaptainJean-Luc Picard's wishes, Pressman ordered the Enterprise to enter a chasm on the asteroid which led to the Pegasus's location, the first time a starship had been taken so deeply within a planetary body. While Pressman was able to retrieve the phasing cloaking device from the Pegasusengineering section, the Romulans used their disruptors to seal the Enterprise within the asteroid, claiming that they were conducting geological experiments. CommanderWilliam T. Riker, another former member of the Pegasus crew, defied Pressman's orders and revealed the existence of the phase cloak to Picard. It was then installed aboard the Enterprise and used to escape the asteroid's interior. (TNG: "The Pegasus")
